Vintage 1960's Camp Postcards Kelloggs Totem Yogi Huckleberry Mice

Lot of 2 cute postcards that appear to have been for a child to send home from camp. 

From the style & code numbers at the bottom are guessing are from 1964 & 1965.

One has Yogi & I think BooBoo piled on top of a colorful totem pole looking a bit concerned about a passing skunk.  Other one has Yogi, Huckleberry, and other Hanna Barbera characters with various camp activities listed.  Backs of both have options for the little camper to mark off - both including the mention of Kellog's products.  A few marks or discoloration on the backs, but are unused and fronts are very nice.  Color Litho made in USA.
